Amit Gupta commented on JCR-4042:
---------------------------------
yeah we need another character as escape sequence prefix. i.e. backslash, then
this could serve as escape sequence for any(other) character.
> Adding Escape Character in GQL

> Key: JCR-4042
> URL: https://issues.apache.org/jira/browse/JCR-4042
> Project: Jackrabbit Content Repository
> Issue Type: Bug
> Components: jackrabbit-jcr-commons
> Reporter: Ankit Agarwal
>
> Currently GQL does not have a escape character. Adding the escape character
> will help in special character cases for example where a search term contains
> both colon(:) and quote(") character.
> for example search string is foo:bar, if term is put in quote "foo:bar" and
> this whole term is considered as a single search value.
> But in case user need to search foo"abc:bar then putting this term in quotes
> won't work. But if GQL will have a escape character, then user can search
> this term using escape character.
